REST stands for representational state transfer. It is a simple stateless programming paradigm that generally runs over HTTP. The emphasis is on machine to machine communication.

// Header file @property (weak, nonatomic) IBOutlet UILabel *temperatureLabel; @property (weak, nonatomic) IBOutlet UITextField *city;

// Implementation file NSString* location = _city.text;

NSString* urlString = [NSString stringWithFormat:@"http://weather.com/weather.php?location=%@", location];

NSURL *restURL = [NSURL URLWithString:urlString];

NSData *myData = [NSData dataWithContentsOfURL:restURL];

NSString *string = [NSString stringWithFormat:@"%.*s", [myData length], [myData bytes]];
